Embodiment Construction

[0014] see figure 1 , figure 1 It is a structural diagram of a preferred embodiment of the method for simulating keyboard input in the present invention. A preferred embodiment of the computer system of the present invention includes a computer and a chip. The computer is provided with a universal serial bus interface. The chip is also provided with a universal serial bus interface connected with the universal serial bus interface of the computer. In this embodiment, the model of the chip is C8051F340. The software program of the preferred embodiment of the method for simulating keyboard input in the present invention is burned in the chip, and the key value information of the keyboard is sent to the computer through the chip, and the computer executes the corresponding key value information according to the key value information. action. When the computer is turned on, but before the operating system of the computer is loaded, the chip sends the data set by the user to t...

Abstract

The invention provides a computer system for simulating input of a keyboard. The computer system comprises a computer and a chip for storing at least one execution key value, wherein the computer reads a key value definition data comprising a plurality of key values and corresponding commands thereof; the chip transmits the at least one execution key value to the computer; and the computer executes the corresponding commands according to the at least one execution key value to stimulate the input of the keyboard. The invention also provides a method for simulating the input of the keyboard. Compared with the prior art, the method for simulating the input of the keyboard and the computer system can realize automatic simulation of the input of the keyboard without an operating system.

Description

technical field [0001] The invention relates to a computer system and a method for simulating keyboard input, in particular to a computer system without an operating system and a method for simulating keyboard input. Background technique [0002] The current virtual keyboards are all software built under the operating system of the computer, through which real keyboard operations are simulated. For example, on a desktop computer, the on-screen keypad program of the Windows operating system can be used as a virtual keyboard like a real keyboard or mouse. On a personal digital assistant (PDA) controlled by a stylus, the user can use the PDA Use the virtual keyboard attached to the operating system to enter text. These keyboards use the features of the system's virtual machine and usually have fewer buttons than a computer's keyboard. However, for a computer without an operating system, a virtual keyboard cannot be implemented. Contents of the invention [0003] In view of...
